A SPATIAL SENSOR SYNCHRONIZATION SYSTEM USING A TIME-DIVISION MULTIPLE ACCESS COMMUNICATION SYSTEM

A spatial sensor synchronization system using a Time-Division Multiple Access (TDMA) communication system, intended for a plurality of entities evolving inside the TDMA communication system, whereby each one of the plurality of entities is intended to comprise a spatial sensor and a tag enabled to communicate in the TDMA communication system, further whereby each spatial sensor is enabled to make a spatial measurement during a determined active time period, further whereby the tags from the plurality of entities are addressed in sequence by the TDMA communication system with a determined sequence period separating two subsequent addresses in the TDMA communication system. Each of the tags comprises electrical trigger output means configured to output an electrical trigger to the sensor of the corresponding entity at the time of being addressed by the TDMA communication system. Each of the sensors comprises electrical trigger input means connected to the electrical trigger output means, and configured to initiate a spatial sensor measurement for each received electrical trigger. A duration of the determined sequence period is equal or greater than a duration of the determined active time period.
